It was a museum where there were few tourists and you could look around slowly! More sculptures than painting. It was amazing and it was really fun!
It was from the basement to the 3rd floor, and it was fairly spacious, so it took nearly 4 hours if I looked slowly.
On the way, I was able to overlook the Roman Forum from the balcony and it was very comfortable.
Large luggage such as backpacks must be stored in lockers. On the way, I was told that if I tried to go back to get my luggage, I couldn't return until I left. I think the locker room is in front of the ticket. Be careful not to forget anything.
